Abstract

In this study, polysilanes were synthesized by electroreduction with different monomers such as $CH_3HSiCl_2$, $PhSiCl_3$, $CH_3SiCl_3$ and $(CH_3)_2SiCl_2$ by Mg electrodes under ultrasonic radiation. The effects of monomers and additives (p-dibromobenzene (DBB), naphthalene (NAPH) and anthracene (ANTH)) on the reaction rate were investigated. Polymerization of $PhSiCl_3$ among the four monomers showed the highest rate. p-dibromobenzene (DBB) was proved the most effective additive. Based on the observations, some possible reaction mechanisms of the polymerization were proposed.
